It's supposed to! (And the mouse works on my Debian Lenny machines without any problem, so this is definitely a bug.).

Does the mouse cursor show up if you switch into windowed mode (The F key toggles windowed/fullscreen)? While you're playing, does right-clicking take you to the profiles menu? What distribution, screen resolution, and window manager are you using?
